I have searched the best Molosses and i have found them:
Short-coated Molossian breeds of medium-large size are the best ones, both strong, quick and good-natured. Above all, among these breeds we can find the following: Bandog, Boerboel, Bull Mastiff, Cane Corso, Dogue de Bordeaux, Great Swiss Mountain Dogs, Fila Brasileiro, Neapolitan Mastiff, Pero de Presa, Rottweiler and Tosa.
Why are these breeds the best ones?
1. They aren't as much feed-demanding as the largest Molosses
2. They are both sufficiently strong and quick
3 . They are good-natured and socialized perfectly.
4. They are good defenders (not too dangerous for a civilized human society like Owtcharkas and Sheep-herding breeds that often attack the throat of an intruder and may kill him or injure severely at least), their defence is adequate and appropriate (they usually do a smaller injury only).
